Introduce the structure and working principle of precision giant magnetostrictive actuator and establish the actuator system object transfer function model so as to design a suitable active disturbance rejection controller (ADRC). According to the model analysis, regard the actuator system as a first-order inertia object with dead time to construct second-order ADRC, use MATLAB for parameter tuning...
Aiming at first-order inertial systems with time-delay this paper presents a new method of auto disturbance rejection control (ADRC) parameter tuning, in which it confirms the corresponding relationship of ADRC parameters for different objects in groups of the ??/T value, and with the method of time transformation and gain transformation. The procedure of different objects parameter tuning is simplified...
